Compare CAN 2.0
UIM24204/24208 are miniature, intelligent stepper motor controllers equipped with CAN (control area network) bus for building up local motor network. By using these motor controllers, user can control multiple motors in real-time. To communicate with these motor controllers, user needs one CAN-RS232 converter (UIM250, sold separately). The UIM250 CAN-RS232 converter communicates with the user devices/controllers through RS232 protocol using ASCII codes. Through this fashion, users can operate these controllers with minor or no knowledge about the stepper motor driving and CAN bus. The structure of the instructions (i.e. commands from user) is simple, straightforward and fault-tolerating.
UIM24204/24208 can be mounted onto 42/57/86/110 series stepper motors seamlessly through corresponding flanges. The thickness of these controllers is less than 14 millimeter. Enclosures of UIM24204/24208 are made of die-cast aluminum which provide a rugged and durable protection to the controller and improve the heat dissipation..
